I. A Brief History of Ginkgo Biloba

The Ancient Origins

Ginkgo Biloba, often referred to as a ‘living fossil’, has a history that stretches back more than 270 million years. To put it into perspective, this majestic tree was already old when the first dinosaurs appeared! It has endured the relentless march of time, surviving even the catastrophic event that led to the extinction of dinosaurs.

Flourishing in the Land of the Rising Sun

Fast forward to a few thousand years ago, and we find that Ginkgo Biloba held a cherished place in ancient Chinese culture. The tree was a common sight in temple gardens, and its nuts were an integral part of traditional Chinese medicine. There’s even a 3,000-year-old tree in the Chinese province of Shandong that is still growing today!

Journey to the Western World

The western world had to wait until the 18th century to get its first glimpse of the Ginkgo Biloba tree. A German botanist, Engelbert Kaempfer, found it growing in Japanese temple gardens during his travels. He brought it back to Europe, where it eventually gained popularity for its beauty and resilience. The tree was then introduced to the United States around the early 19th century.

Ginkgo Biloba in Modern Times

Today, Ginkgo Biloba is cherished worldwide, not just for its unique fan-shaped leaves and ornamental value, but also for the medicinal properties of its extracts. It’s a symbol of longevity and endurance, often planted in urban areas due to its ability to withstand pollution.

We’ve certainly come a long way with Ginkgo Biloba, from ancient temple gardens to modern cities around the globe. This remarkable tree, unchanged for hundreds of millions of years, continues to thrive and offer its benefits to humankind, a testament to nature’s incredible ability to endure. Now, let’s transition to the botanical side of things, and take a closer look at what makes this tree so unique.

The Unmistakable Form

If you ever come across a Ginkgo Biloba tree, its distinctive look will likely catch your attention. Standing tall at about 20-35 meters (66-115 feet), it often has an angular, irregular crown when mature. Its bark, grey and furrowed, adds to the aged charm of the tree.

A Leaf Like No Other

Ginkgo Biloba’s leaves are a marvel of nature. They are fan-shaped, usually 5–10 cm (2.0–3.9 in) in diameter, and divided into two lobes, hence the name “biloba,” meaning “two-lobed.” These leaves, bright green in the spring and summer, turn a brilliant yellow in the fall, creating a spectacular display.

A Tale of Two Sexes

One fascinating aspect of Ginkgo Biloba trees is that they are dioecious. In simple terms, there are separate male and female trees. The males produce small pollen cones, while the females bear ovules that, when fertilized, turn into seeds. And it’s worth mentioning, the seeds of the female Ginkgo Biloba tree have a distinctive smell, which some find less than pleasant!

The Longevity Secret

Ginkgo Biloba has a knack for survival. It is incredibly resistant to disease and pests, which explains its impressive longevity. Some specimens have been found to live over a thousand years! The tree’s resilience can also be attributed to its deep root system and ability to sprout readily from the trunk and roots if damaged.

So there you have it – a snapshot of Ginkgo Biloba’s unique botanical features. Its unique leaves, distinct sexual dimorphism, and remarkable resilience all contribute to its status as a true botanical wonder. Now, let’s transition to the next part of our journey and explore the cultivation practices for this ancient tree.

Planting Your Own Living Fossil

Ginkgo Biloba isn’t just for park and street landscapes; you can grow one in your backyard! When you’re ready to plant, choose a location that gets plenty of sun and has well-draining soil. This tree isn’t picky about pH, so it will be comfortable in anything from slightly acidic to slightly alkaline conditions.

From Seed to Tree

Starting a Ginkgo Biloba tree from seed can be an interesting project. The seeds should be cleaned and stratified, which means exposing them to cold and moist conditions for a certain period. After stratification, you can plant the seeds in a pot filled with a good-quality potting mix, and before long, you should see a small ginkgo seedling poking through the soil.

The Waiting Game

Patience is key when growing Ginkgo Biloba. These trees grow slowly but surely, often taking 20 years or more to reach maturity. However, remember that it’s worth the wait! Once established, your Ginkgo Biloba tree will be a low-maintenance, long-lasting addition to your landscape.

A Friendly Tip

As we’ve mentioned earlier, female Ginkgo Biloba trees produce seeds that have a strong, unpleasant smell. To avoid this, many gardeners choose to plant male trees. If you’re purchasing a young tree, consider opting for a named male cultivar to prevent any smelly surprises down the line.

In essence, growing a Ginkgo Biloba tree can be a rewarding experience, combining the thrill of nurturing a living fossil with the beauty of watching it flourish year after year. Now that we’ve covered the basics of cultivating Ginkgo Biloba, we’re ready to explore the many traditional uses of this magnificent tree.
